ROLL HOLDING MAGAZINE Filed June 29, 1932. 3 Sheets-Sheet 5 6/ W ff/VENTUJE ATfYs Patented Dec. 5, 1933 UNITED STATE-S PATENT OFFICE 1 Claim.

My inwention relates to a roll-holding magazine for duplicators.

One of the objects of my invention is to provide such a magazine in which the rolls are readily accessible and mounted in such a way that they will not get out of order.

A further object is to provide a roll-holding magazine combined with a duplicator in such a way that a minimum of floor space is required and a maximum of convenience in handling the rolls is obtained.

Further objects will be apparent from the description and claim.

In the drawings, in which an embodiment of my invention is shown,

Figure 1 is a perspective view showing a rollholding magazine combined with a duplicator;

Fig. 2 is a horizontal sectional view below the duplicator and above the main body of the rollholding magazine;

Fig. 3 is an enlarged perspective view of the spindle-receiving pocket;

Fig. 4 is an enlarged view of a detail of the frame construction;

Fig. 5 is an enlarged sectional view of another detail of the frame construction;

Fig. 6 is a section on the line 6-6 of Fig. 7;

Fig. 7 is asection on the line 7-7 of Fig. 6; and

Fig. 8 is a perspective view of a detail of the roll-holding magazine.

Referring to the drawings in detail, the construction shown comprises a swivel magazine 1 having provisions for holding a number of the gelatin rolls 2, a duplicator machine 3 mounted above the roll-holding magazine, and a framework 4 within which the roll-holding magazine 1 is mounted for swivelling movement and above which the duplicator machine 3 is mounted. Suitable trays 5 may be provided also mounted on the framework 4 for holding the sheets before and after they have been operated on by the dupli-,

eating machine.

The roll-holding magazine 1 is mounted for its swivelling movement by, means of a rotatable by means of upper and lower horizontal transversely-extending tubular bars 9 to which the rec- V tangular framework 4 of the magazine is secured.

The bearings 7 and 8 for the vertical shaft 6 are supported by transverse horizontally-extending 7 frame members 10 extending from side to side between the horizontal frame members 11 of the main framework 4.

In order to insure that the roll-holding magazine shall come to rest in proper position, the upper end of the vertical shaft is provided with a positioning disc 12 having four notches 13 therein for cooperation with a detent 14 pivotally mounted at 15 on the upper cross bar 10. A coil tension spring 16 is provided to hold the pivoted detent 14 in operative position. The construction of the detent 14 and notches 13 is such that the disc 12 can rotate in only one direction, as shown in Fig. 7, thus insuring that the operator will always know what rolls have been used and preventing confusion in selecting the rolls.

The gelatin rolls 2 are mounted on spindles, the projecting ends 17 of which are slipped into sheet metal pockets 18 (Fig. 3) secured to the upright corner pieces 19 of the magazine. To facilitate the placing of the rolls in the magazine, the pockets may be provided with an inclined guide portion 20 which will cause the projecting end of the spindle to slide into the semi-circular pocket 18v In use, the rolls may be removed and replaced from the front or right-hand side of the machine, the magazine being turned to bring the desired roll or rolls into convenient position for access.

The swivel magazine itself comprises the plurality of vertical sheet metal corner pieces 19 on which the roll-supporting pockets are mounted, and a plurality of horizontally-extending tubular frame members 20 uniting the vertical corner pieces to each other to form a rigid rectangular construction. Each vertical corner piece 19 comprises a pair of channel members 21, as shown in Figs. 3 and 8, secured together back to back by welding, or in any suitable manner, the spindle-supporting pockets 18 being secured to the flanges of the channel members.

The sides of. the framework are united by means of four transversely-extending tubular cross pieces 22 through which clamping tie rods 23 extend, as shown in detail in Figs. 2 and 5, the tie rods being tightened by means of nuts 24 threaded on their ends. The transversely-extending upper support 10, on which the bearing 7 for the vertical shaft 6 is carried, may be secured to the upper side frame member 25 by means of a curved brace member 26, as shown in Figs. 6 and 7.

The duplicating machine itself may be removably mounted on the main framework. For this purpose, the framework is provided with four pockets 2'7, as shown in detail in Fig. 4, for receiving the foot portions 28 of the duplicating macorner posts, supporting means for a duplicator mechanism carried by said posts, a swiveled rollholding magazine carried by said frame having its axis vertically and centrally positioned with respect to said corner posts, said magazine having means for supporting four tiers of rolls with each tier adjacent the space between a pair of corner posts, each pair of posts being spaced to permit the rolls to be removed and replaced readily.
